Barbara Olson found dead in garage Wednesday

Two Sheboygan boys were charged Friday morning in the killing of a 78-year-old Sheboygan Falls woman.

One of the boys, Antonio Barbeau, was her great-grandson. They are both 13-year-old eighth-graders.

"This is a very disturbing allegation, particularly as to the details as to how this crime occurred," Sheboygan County District Attorney Joe DeCecco said.

Barbara Olson was found dead in her garage Wednesday afternoon.

Police said Barbeau initially hit his great-grandmother in the head with the blunt end of a hatchet, knocking her down. He then hit her several more times. The other boy, Nathan Paape, then hit her twice with a hammer, and then, Barbeau hit Olson in the head with the blade of the hatchet, police said.

Prosecutors said the boys went to the house with the intent to kill her. They also stole some of her jewelry and other items, police said.

The boys are being charged as adults with first-degree intentional homicide.

"It's a very adult crime. It's the adult crime," DeCecco said.

The boys killed Olson inside the house and then dragged her into the garage, police said. They then stole her car, parked it in a Sheboygan bowling alley and had pizza at a nearby pizza parlor, according to the criminal complaint.

Afterward, the boys bought wipes to clean up the car and left it unlocked with jewelry showing, hoping someone else would steal it and be accused of the slaying, prosecutors said.

DeCecco was asked after the hearing if the boys seemed remorseful.

"Well, I'm not sure how remorseful. In the interviews I heard and reviewed, they were matter-of-fact about what they'd done. I think the fact they both went out and got a pizza right after killing this woman indicates some of their extreme lack of concern," DeCecco said.

The boys are being held with bail set at $1 million.

Barbeau's mother was in court but didn't talk afterward.

Wisconsin law was changed in 1995, allowing adult charges for suspects as young as 10 years old.

Even then, 17 years ago, there was a noticeable and growing trend of violent crimes committed by children.
